To all whom it may concem:

ne it known that LAMA-naif B. Liann., acitiaon of the United Staten, residing at Waynesboro, in the county of Franklin und Stato of Pennsylvania, have invented certainneii' and useful Im irovcnients in ('-utterHeada, of which the ollowing is a specioation Hy laid invention consists in certain ini- :go provlnents in the details of construction 'lb atraction and one wherein `the cuttin 20 Bdarting to the aocompan in arrangement of rts 'of cutter-heads for thmads oliia screws, bolts, ctc., .w a cutter-head for the. pur is phvidod which is of durable and rigid coinic may conveniently and4 accurately adjusted forv ditl'mnt aia of work and readily opened and closed, all as will be hereinafter ma'. fully described and claimed.
